IMPROVED MHINB FOR SHAVING HILDES-l To ALL PERSONS To WHoM THESEPRESENTS SHALL COME:

Be it. known that I, T. F. WESTON, of Salem, in th'e county of Essex,and State o'f Massachusetts, have invented certain new and usefulimprovements in' Machines forReducing or Shaving Hides' to a smoothsurface preparatory to the final operation of finishing; and that 4thefollowing'description, taken in connection' with the accompanyingdrawings hereinafterY referred to, forms a full and exact specificationof the same, whereirrI have set forth the nature and principles of mysaid improvements, by which my invention may be distinguished from allother of a similar class, together with such parts as I claim and desireto have secured-to me by Letters Patent.

The present invention consists in certain new and useful improvements inmachines for reducing or shaving hides toa smooth surface preparatory tothe final operation of finishing; Various devices have heretofore beenexperimented with for the purpose of accomplishing this result, but inall such cases a knife or scraper has been employed which had but onemotion, imparted t'o it, viz, a motion longitudinal with the bed upo'nwhich the leather was placed; But this movement has failed to imitatethe peculiar manipulation of an operator skilled in this branch of themanufacture, as it is necessary to impart to the cutting tool both alongitudinal and transverse motion, whereas,l if solely a forward orlongitudinal direction is given to the tool, the effectupon. the surfaceis to tear and roughen its surface and fibres instead of 'to shave orsmoothi-t. In my improved machine I employ a cutting or scraping tool towhich are imparted two motions, one which is'longi/tudinalto thebednponwhich the leather isv placed, and the other transverse to theAsame, or nearly so, the result being to 4produce the drawing eut that ispeculiar to the movements of the hand operator, and also accomplish thework with' much less time and expense. In the' accompanying plate ofdrawingsl Figure l is a plan or top view of my improved machine.

Figure 2 is a side elevation. of the same. v

Figure 3 is an enlarged vertical section showing certain parts of themachine in detail.

aa, in the drawings, represent an inclined table or platform Asustaininga bed-plate, b b; this bed-plate to be made of metal, glass, or anyother suitable material, and can also be made adjustable in' a verticaldirection. On the bed-'plate bb is. placed the leather to' be scraped orshaved. This is effect-eil by means of a cutter, c, which has both alongitudinal or forward movement across tjhe bed-plate b b, and a rotarymotion imparted .to it, follows: The cutter' c is attached 'to a shaft,d, having its bearings in a projection of a connecting-rod, ce. Theconnecting-rod ee is-.sustained by an arm, f, pivoted' at g and h, andattached to, a wheel, t', actuated by a shaft, k, to'which m'otion canbe imparted in any suitable manner; thus'the revolution of the wheel z',by means ofthe connecting-rod e e, will give a forwardiaml buckmovementto the cutter c', causing the latter to be brought in contact with theleather during its forward or downward movement across the bed-plato bb, but'l relieving or lifting it`from the same while returning'.v Therotary movement is imparted to the cutter c by t'he following means: Apulley, l, upon the pivot m o f the .connecting-rodee,y conveys motionby means of an endless belt or band, tn,.to theshaft d, a bolt or bandfirst passing over small guidingpulleys oo. n

In the foregoing d'escription. and accompanying drawings I haveillustrated acircular tool or scraper to which both a forward 0rlongitudinal motion and a rotary movement are imparted, but it will beevident that the same e'ec'tjcarrbe attained bythe use, for instance, ofastraight or rectangular-shaped tool which has both 4 a forward orlongitudinal. movement, and a lateral 'one transmitted to it by any ofthe well-knownmechanica'l devices usually employed lfor such purposes.yAn endless belt-or band of flexible metal having similar motions mightalso be used, as will be manifest without furtherl explanation.4 l

I claim the use of the cutting, shaving, or scraping tool, having suchmotions imparted to it by any suitable arrangementof mechanical devicesas to produce a drawing cut upon the surface of the leather, ashereinvbefore set forth and for the purpose specified.
